JOHN G. SGHNEIDEB, OF PLAINFIELD,1\'I'EW JERSEY.

DOOR LOCK OB FASTENER.

Application filed. July 24, 1915.

To all whom it may concern:

Be it known that 1, JOHN G. SCHNEIDER, a citizen of the United States,and residing at Plainfield, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in Door Looksor Fasteners, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to door looks or fasteners and particularly todevices of this class of the wedge type, and the object thereof is toprovide an improved device of this class by means of which a door may besecured in a closed position, or whereby the door may be swung partiallyopen and pre vented from further movement so as to provide means forventilation and also prevent a person from entering a room or apartmentwhen the door is ajar or partially open.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a sectional view showing myimproved door securing device and showing the method of its operation;Fig. 2 a plan view of my door securing device detached and shown in thesame position as in Fig. 1; and, Fig. 3 a side edge view showing theseparate parts of the device folded together.

In the drawing forming part of this specification, I have shown at a apart of a floor of a building, apartment or room, and at b a part of adoor leading into the apartment or room, and at Z1 a part of a doorsill, and, in the practice of my invention, 1 provide a device of theclass specified comprising a metal plate 0 of predetermined length, preferably from four to six inches, and said plate is wedge-shaped in format one end as shown at 0 and the other end thereof is provided with asupplemental plate or angle piece 0 having projecting. teeth 0*, in theconstruction shown.

The supplemental plate or angle piece 0 may be of any suitable length,depending on the length of the plate a, and is preferably of a length ofabout one-third that of said plate a, and said supplemental plate orangle piece is formed separately and connected Specification of LettersPatent.

with one end of the plate 0 as shown at 0 by means of a hinge which willpermit it to turn through an arc of approximately 245, whereby the part0 may be turned backwardly and over and onto the part 0 as shown in Fig.3, and this enables the device to be packed in a small compass so as tofacilitate its shipment in boxes or packages and permit of its beingconveniently carried.

In order to secure the door in a closed position, the wedge-shaped end 0of the part c is passed beneath the door as shown in full lines in Fig.1, while the teeth 0 of the part 0 are pressed into the floor, or intothe carpet covering the floor, and this will prevent the door from beingswung inwardly, or into an open position, as will be readily understood.

vVhen it is desired to use my improvement for holding the door againstbeing swung entirely open, or to permit it from being partially open forventilation or other purposes, the securing device is placed in theposition shown in dotted lines at c in Fig. 1, in which position thedoor may be swung partially open as indicated in dotted lines at 5 lheteeth c on the part 0 of my improved door securing device are notabsolutely necessary especially when the device is used on a carpetedfloor, and it will be un' derstood that the angle of the part 0 to themain plate or part 0 may be varied within certain limits when in use,without effecting the operation, or the results thereof, and the degreeof this angle will depend upon the construction of the hinge c andalthough mj improved door securing device may be compactly foldedtogether for packing shipping or other purpose, as shown in Fig. 3, thepart 0 cannot turn or be turned in the direction of the arrow 00 Fig. 1,further than a predetermined point fixed by the construction of thehinge 0 Having fully described my invention what I claim as new anddesire to secure by Letters Patent, is

A door securing device of the class described comprising a main plate ofpredetermined length and one end of which is wedge-shaped in form, theother end of said plate being provided with a shorter supplemental platemember connected therewith by a hinge which will permit it to turn inpresence of the subscribing witnesses this one direction only through anarc of 245 twentieth day of July, 1915 whereby said supplemental platemember may be folded onto the main plate member 1 JOHN SCHNEIDER 5 orturned at a predetermined angle thereto. lVitnessesr 1 In testimony thatI claim the foregoing asv ,7 HENRY LIEFKO, my invention I have signed myname in 'E. V. WALDORF. 1
